AUTOMOBILE-LOCK Application filed January 31, 1919.

To aZZ whom it may concern:

Be it known that we, ALEXANDER M.

. MCGIFF, a citizen of the United States, and

a residentof the city, county, and State of New York, and HARRY CHINSKY,a citizen of the United States of America, and a resident of the city,county, and State of Xew York, have invented certain new and useful1mprovements in Automobile-Locks, of which the following is aspecification."

This invention relates to a lock for automobiles, or self propelledvehicles in general, whereby the propelling mechanism may be lockedagainst movement during absence of the driver.

The invention has for an object to provide a novel and simple lockingdevice capable of easy attachment-to automobiles of ordinary type. i

For further comprehension of the invention and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a part side elevation and part longitudinalsection of an automobile having the invention applied thereto;

Fig. 2 is a fragmentary perspective View thereof;

Fig. 3 is an enlarged detail view of the locking device, this view beingtaken on the line 33 of Fig. 4;

Fig. 4 is a transverse section on the line 4-4 of Fig. 3;

Fig. 5 is a detail View showing the ratchet wheel on the drive shaft andthe keeper engaging therewith; V

Fig. 6 is a similar view with the keeper withdrawn;

Fig. 7is a detail elevation with the casing "partly broken away, of thecombination locking mechanism;

' Fig. 8 1s a plan view thereof, partsbeing showrrip horizontal section.The body of an automobile of ordinary construction is shown at 1, thedrivers seat at 2, themotor at 3, this latter being connected by theusual transmission gearing 4 and universal joint 5 to the drive shaft 0.

which connects in the usual manner to the rear wheels, one of which isshown at 7.

Our improved locking device comprises a casing 10 secured as by thebolts 11 to the Patented Dec. 9, 1919.

wall 12 extending up from the floor 13 of the automobile. A rack bar 14-extends vertically through this casing, being guided at upper and lowerends in suitable guide brackets 15 and 16. and has formed integral withits lower end a pair of spaced teeth 17 which are adapted to engage aratchet wheel 18 rigidly fixed to the drive shaft 6. This ratchet wheelis here shown as made up of two halves secured together by the bolts 19.

A pinion 25 meshes with the teeth of the rack bar ll, this pinion beingmounted on a stub shaft 26 which extends between and-is ournaled in, therear wall of the casing 10 and an angle bracket 27 fixed, as by screws28, to the said rear wall. A lost motion connection is provided betweenthe pinion and shaft as indicated by the key 29 on the shaft projectinginto widened groove 29' in the pinion boring. Secured also upon thisstub shaft 26 is a bevel pinion 3O meshing with a second bevel pinion 31on the lower end of a spindle which is journaled at its lower end in theangle bracket 27 and extends up wardly centrally through a cylindricalcas,

ing 33 mounted on top of the casing 10, this casing 33 containing myimproved combination lock whereby the spindle, and in consequence therack bar 14, is locked in position. The upper end of the spindleprojects through the top of the casing and is pro vided with a thumbpiece 32 for adyustmcnt.

As here shown a hook 34 projects horizontally from the spindle 32 belowa circular flange 35 fixed on a sleeve 36 surrounding the spindle and.extending downwardly through the top of the casing 33 and having anextcrionknob 37 for adjustment. The end of the hook 3% projects acrossthe face of a pawl 38 pivoted as at 39 on the flange 35 and pressed backor out, against a stop 40 by a spring 41. 'ihe periphery of the flange35.

is formed with a number of unevjen teeth 42. A disk 45 is pivoted upon astud 46 on the bottom of the casing 33, this disk lying in acommonhorizontal plane with the flange with its periphery close to that of thelatter parts adaptedto permit of forwejrd movement of the flange by astep by step movement as the disk is successively moved to predeterminedpositions, means whereby the disk may be set in the said predeterminedpositions, and a member fixed to said spindle and coiiperating with saidflange where- 1S prevented.

In testimony whereof,

we have signed 10 our names to this specification.
